만성 폐색전증으로 혈전 제거술을 하고 난 다음 기관지내 대량 출혈은 빈도는 적으나 상당히 높은 사망률을 보이는 합병증 중의 하나이다. 기관지내 대량 출혈이 생겼을 때 체외 막 산소화 장치와 각각 다르게 조절한 인공호흡기 2대를 이용하여 특별한 휴유증 없이 잘 치료한 경험을 하였기에 보고하는 바이다.

Primary angiitis of the central nervous system (PACNS) is a rare vasculitis in the central nervous system. Herein, we report a case of diagnosis and treatment of necrotic pattern PACNS, which was difficult to differentiate from a brain abscess. A 19-year-old male presented with blurred vision and a headache. Brain MRI revealed irregular rim-enhancing necrotic masses with central diffusion-high signal intensity in the corpus callosum and peripheral diffusion-high signal intensity in the left parietotemporal periventricular area. Susceptibility-weighted imaging revealed multiple punctate hemorrhages in the lesions. The patient was diagnosed with unusual abscess or tumefactive PACNS. Therefore, we initially treated the patient with antibiotics to rule out brain abscess. However, the brain lesions did not improve on follow-up MRI after the antibiotic treatment. Surgical biopsy was performed, and the histopathological diagnosis was PACNS with a necrotic pattern. The necrotic lesions became smaller on follow-up MRI after high-dose corticosteroid treatment.

Angiosarcoma is the most common primary intracardiac malignancy, but many published papers have reported it to be rather rare. The prognosis of angiosarcoma is known to be very poor, and the treatment of choice has been surgery until recently, but many centers currently tend to try multi modal therapies, including chemotherapy and radiotherapy. In this report, we present a rare case in which an intracardiac angiosarcoma could have threatened the patient's life in short time by the rapid progression of the tumor, which caused right atrial rupture.

The present study was conducted to examine the differences and correlations between verbal fluency and story comprehension according to the working memory(WM) capacity, and to find out what WM factors influence the linguistic competence in Alzheimer's disease(AD) and vascular dementia(VaD) groups each consisting of 15 patients. The results of their performance produced firstly significant differences in phonemic fluency, story comprehension, delayed recall and recognition task between the two groups. Further analysis shows that VaD group had significant correlations between the scores of story comprehension and the recognition test scores additionally. These findings suggest that it is possible to differentiate the two groups even by story comprehension tasks and WM. In conclusion, the clinical application of the results is likely to contribute to appropriate treatment plans and effective interventions for elderly with AD and VaD as well as to improve the classification criteria for both types of dementia.

Deep vein thrombosis (DVT) is a common disease. However, May-Thurner syndrome, which is the cause of DVT, is an uncommon processes in which there is an impaired venous return due to compression of the left iliac vein by the overlying right common artery. This condition results in a left iliofemoral deep thrombosis and severe leg edema. It is, therefore, called iliac compression syndrome. Catheter-directed thrombolytic therapy of acute extensive iliofemoral DVT and balloon angioplasty with venous stenting are recommended. Two cases with history of left leg swelling are diagnosed as May-Thurner syndrome, which was demonstrated by venography. We successfully treated the patients with thrombolysis, balloon angioplasty, and stent insertion at the site of common iliac vein compression. Therefore, we report the cases with overall review of the literature.

최근 교통사고의 증가, 심폐술의 보편화 및 보조호흡을 필요로 하는 환자의 증가에 따라 경구적 혹은 기관절개술을 통해 기관내 삽관을 장기간 유치하는 경우가 많아져서 이에 따른 합병증으로 기관협착증의 빈도가 높아지게 되었다. 기관내 삽관후 기관협착증을 초래하는데에는 관의 외경, 삽관시 외상, 삽관유치기간, 기계적 보조호흡시 관의 이동, cuff 의 압력 등의 요인이 작용한다. 이러한 요인에 의해 기관내 삽관을 장기간 유치시 기관점막에 대한 지속적인 압박으로 점막하부의 압박괴사 및 혈관의 폐쇄로 인해 기관연골의 무혈성 괴사를 초래하여 환상의 기관협착이 병발하게 된다. 기관협착증에 대한 치료방법으로서는 여러 가지가 있으나 환상의 기관협착증인 경우는 협착부위의 절제 및 단단문합술을 시행하고 절제부위가 광범위한 경우는 release technique 을 이용하여 문합부위의 장력을 줄여주는 것이 효과적인 치료방법으로 알려져 있다. 저자들은 최근 기관내 삽관후에 병발한 환상기관협착증 3례(다발성 골절 1례, 기관지 천식 1례, 약물중독 1례)에 대해 기관절제 및 단단문합술을 경험하였기에 보고하고자 한다.

An 8-year-old castrated male domestic shorthair cat (Case 1) and 3-year-old castrated male Siamese cat (Case 2) was presented with acute paresis of the hindlimbs, constant open-mouth breathing, and hemoptysis. Heart murmur (Case 1) and gallop sound (Case 2) was ausculated on the left heart base. Radiographs revealed alveolar infiltration of the caudodorsal lung lobes with aerophagea in Case 1 and prominent cardiomegaly in Case 2. Marked concentric hypertrophy of the ventricular septum and free wall, and left atrial enlargement was detected through echocardiography in both cats. Based on the examinations including echocardiography, those cats were diagnosed as hypertropic cardiomyopathy. Abdominal ultrasound revealed echogenic material in the aortic trifurcation region, aortic thromboembolism (ATE). Although prognosis of those animals was guarded, interventional therapeutic approach through direct endovascular thrombolytic therapy was attempted. ATE was visualized through angiography; however dissolving the embolus using interventional thrombolytic approach was not successful due to the extensive thrombus.

An immature tooth with infected pulp has numerous potential complications. Conventional apexification with calcium hydroxide has several disadvantages, including susceptibility to tooth fracture. This method does not promote continual root development. Pulp revascularization of a necrotic, immature permanent tooth will allow further development of the root and dentinal structure. Disinfection of the root canal system is a prerequisite for pulp revascularization and tissue regeneration. A combination of antibiotic drugs (ciprofloxacin, metronidazole, and minocycline) is effective for disinfection of necrotic pulp, and has been used successfully in regenerative endodontic treatment. These case reports involve the treatment of 3 immature permanent teeth with necrotic pulp using a 3-Mix paste and mineral trioxide aggregate. All cases showed the notable apical maturation with closure of the apex and increased thickness of dentinal walls. This approach suggests a paradigm shift in treating endodontically involved immature permanent teeth from the traditional apexification with calcium hydroxide to the conservative approach by providing a favorable environment for tissue regeneration.

Purpose: To evaluate whether early visual acuity response at 4 weeks after the first intravitreal anti-vascular endothelial growth factor (VEGF) injection or 4 weeks after the third injection in neovascular age-related macular degeneration (nAMD) is associated with 12-month follow-up outcome. Methods: Thirty treatment-naive patients (30 eyes) with nAMD, treated with intravitreal anti-VEGF, were retrospectively included. Initially, all patients were injected at least three times for three consecutive months and followed up with a pro re nata regimen for at least 12 months. The relationship between 4 weeks after the first and third anti-VEGF injections in visual acuity response was explored, including the mean change from baseline in best-corrected visual acuity (BCVA). The mean change in BCVA was classified into three groups according to visual improvement: <1, 1-<3, or ${\geq}3$ logMAR line(s) in BCVA. The associations among baseline characteristics (gender, age, duration of symptoms, initial BCVA, central macular thickness, and intraocular pressure) and visual acuity responses 4 weeks after the first and third anti-VEGF injections were also assessed. Results: The proportions of eyes with <1, 1-<3, and ${\geq}3-line(s)$ improvement at 4 weeks after the first injection were 6 eyes (20%), 7 eyes (23.3%), and 17 eyes (56.6%), respectively. The proportions of eyes with <1, 1-<3, and ${\geq}3-line(s)$ improvement at 4 weeks after the third injection were 9 eyes (30%), 9 eyes (30%), and 12 eyes (40%), respectively. A BCVA response ${\geq}3-lines$ improvement at 4 weeks after the third injection showed significant associations with ${\geq}3-line(s)$ improvement and BCVA response at 12 months in multiple logistic and linear regression analyses (p = 0.04). Conclusions: In this study, BCVA response ${\geq}3-lines$ improvement at 4 weeks after the third injection showed a significant association with ${\geq}3-line(s)$ improvement and BCVA response at 12 months.
